In a 12 to 14 inch saute pan, heat 2 tablespoons of the olive oil over medium heat. Add the onions, garlic and anchovies and cook over medium heat, stirring occasionally, until the onion and garlic are softened and the anchovies have begun to break up. Turn the heat up to high and add the squash cubes. Toss over high heat for 5 minutes, or until the cubes are tender and browned at the edges. Season with salt and pepper and remove from heat.
Season chops with salt and pepper. Brush the chops with 2 tablespoons of the olive oil and place on the hottest part of the grill. Cook to medium rare, 6 to 8 minutes per side.
Place a chop on each of four warmed dinner plates, pour the zucca mixture over, top with bread crumbs and serve immediately.
